At check-in, PreCheck enrolled passengers will not have to go shoeless and beltless, they can leave liquids and laptops inside carry-on luggage, as they mosey a reserved fast path through the security area.

Expedited screening does not guarantee immunity from standard security restrictions, however. Random searches and unexpected measures are still a possibility.

The human head was found Tuesday afternoon, the first hand was found Wednesday morning and the second hand was found Wednesday afternoon. Police believe the murder occurred elsewhere and the body was dumped in the park.

"We're hoping we can find more remains," LAPD Cmdr. Andrew Smith said, according to the Times.

L.A. Weekly posted a breakdown of Elizabeth Ibarra's Facebook on Wednesday. The 19-year-old is suspected of luring Francisco Rodriguez onto his front lawn, then shooting and killing him.

Dubbing it her "telling Facebook trail," L.A. Weekly posted several screenshots showing new, if confusing, layers of the relationships between Ibarra, Jason Schumann (the suspected shooter) and Rodriguez.

One post features a picture of the future suspected shooter with a baby, captioned by Ibarra as "DELANO WiTH HiS DADDY :'] ♥ H0W AD0RABLE!!" She then went on to call him a "sick cheating son of a b----" in the comments section. Another post highlights future victim Rodriguez making a suggestive comment on a picture of Ibarra from July of last year.

"The hand is still where they found it, they're taking pictures of it, and they'll take it down to the coroner's office," said Cmdr. Andy Smith.

The L.A. Times reported this morning that police sources said the head was from an Armenian male in his 40s, but Smith said, "As we've taken a look at that, we're saying undetermined now. It could be European or Armenian, but they're saying undetermined." The age estimate has also shifted to between 40 and 60.

Police are combing missing persons reports, among other things, throughout the county to try to identify the person the head and the hand belongs to.

Itzcoatl Ocampo, the 23-year-old former Marine accused in the brutal serial killing of four homeless men in Orange County, appeared in a cell on Tuesday at a Santa Ana arraignment that lasted less than five minutes before being postponed.

Ocampo's lawyer asked for a continuance, saying he was given only 15 seconds to speak with his client through a food slot, and did not have enough information to enter a plea. Jail officials also had not conducted a psychological evaluation on Ocampo, reports KPCC's Adolfo Guzman-Lopez.

"He was curled up in a ball under a blanket in underwear, no shirt, no pants," Longwith said. "He looked like a wet cat — a scared, wet cat. It wasn't much conversation," said Ocampo's lawyer of his brief visit on Tuesday, reports the L.A. Times.

Orange County District Attorney Tony Ruckauckas called Ocampo a "thrill kill" case — a person who kills "to see what it’s like to make those kills and he gets a thrill out of it." He expects Ocampo to plead insanity.
